I have the Model 20 in 10mm.It is a pretty stout round.Especially if you use the Double tap ammo.The 29 in compact will be even meaner to shoot .Probally want to get the mags. with the exta length for the last couple of fingers.My buddy has the Model 30 in .45 acp.It is not as bad,but still need the extra length on the mag.
I don't have a 29 but have fired my brother in laws quite a bit. The 10 mm is a pretty stout round in a full size pistol, so as Swampman stated you will definatelyfeel it inthe G29.
